I have to agree with Cliff and change my original opinion, the centre seam looks like its mismatched and if so its a very nice flg 90..however i also think i see a glimpse of flame in one shot of the cavity... so inconclusive, but need sharper pics of the center seam to be 100%

This shot almost looks like some flaming down the sides.
Issue is, that router cut on those walls are not super smooth so that really obscures any visible flaming, ever if it were 100% conclusive that the top is solid._________________

i also think i see flame in the walls, but if the center seam is off line it has to ba a veneer.. it is a lovely looker and i would be interested no matter what model..._________________http://www.japanguitars.co.uk

It honestly looks like you can see a faint line traversing down from the top center seam but hard to say.
The grain in the cavity looks continuous however but that could have just matched up perfectly._________________
